Panic button IP device

ABSTRACT

A device for requesting emergency assistance having a built-in panic button that may be implemented in hardware or software. The device may be in a wearable configuration so that the user in need of emergency help can carry the device on the user&#39;s person, or the device may be located at a fixed location accessible by the user. Activation of the panic button by the user results in the device automatically transmitting one or more TCP/IP messages over the Internet to an emergency service center requesting emergency help and identifying the user requesting such help. The emergency service center may also communicate, e.g., via Internet e-mail, with the device (and, hence, with the user) prior to dispatching emergency help. The resources of the Internet may thus be advantageously harnessed to allow users to request emergency help using the device of the present invention. Internet-based emergency help message delivery may be useful in many situations, for example, when the person in need of help is mute, disabled or in a situation that prevents that person from orally requesting emergency help.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention broadly relates to emergency reporting devices,and more particularly, to a device that employs TCP/IP (TransmissionControl Protocol/Internet Protocol) messaging to report a user'semergency condition to an emergency service center (e.g., the police).

2. Description of the Related Art

FIG. 1 illustrates a typical prior art emergency reporting arrangementusing a telephone 10. A person in need of emergency help dials adesignated emergency reporting number (e.g., ‘911’) to connect to anemergency service center (ESC) 12. The emergency service center 12 maybe a 911response center, a police station, a hospital, a fire station, acombination of these places or any other location equipped fordispatching emergency relief. A carrier network 14 may electricallyconnect the telephone 10 to a receiving apparatus (e.g., an operatorheadset receiver) at the ESC 12. The carrier network 14 may include,individually or in combination, the plain old telephone system (POTS),the more advanced public switched telephone network (PSTN), or awireless communication network (e.g., a cellular phone network) when thetelephone 10 is, for example, a cellular phone (“cell phone”).

Instead of dialing all the digits contained in the designated emergencyreporting number (e.g., ‘9’,‘1’,‘1’), a user may instead “speed dial”the number by programming a single key on the telephone 10. In thismanner, the user need not press individual digits of the phone number,but, instead, may need to press only a pre-marked speed dial key. Somemodem cell phones come equipped with a “button” or key on their keypadsthat is dedicated to dial a predetermined emergency phone number (e.g.,‘911’).

Another emergency reporting device is shown in FIG. 2, which depicts aprior art “panic button” 16 in communication with the emergency servicecenter 12. The panic button 16 may be broadly categorized as a wearablewireless transmitter that finds applications in situations when the usermay not easily access the telephone 10 or when the user is not able todial the ESC's 12 telephone number. Users of the panic button 16 mayinclude, among others, elderly people and people with delicate health.Normally the user wears the panic button 16 around the user's neck andpresses the panic button when an emergency condition arises. The panicbutton 16 wirelessly transmits an “alarm signal” to a base unit orreceiving device (not shown) attached to the user's phone line. Thealarm signal instructs the base unit to initiate a phone call to apreprogrammed phone number, usually the phone number of an establishmentor company that provides support services and maintenance for such panicbuttons in a given geographical area.

A support service provider (SSP) 18 receives the phone call from thebase unit of the panic button 16 via the carrier network 14. The baseunit may send over the phone line an identification code or numberpre-assigned to the panic button 16 by the SSP 18. Therefore, anoperator at the SSP 18 may immediately compare the receivedidentification code with a customer database to identify the user of thepanic button 16. Upon identifying the user, the operator in the SSP's 18facility may place a phone call to the ESC 12 giving requisiteinformation (e.g., the name of the person in distress, the locationwhere help is needed, any known medical history of the person requiringemergency help, etc.) to the operator or relief help dispatcher at theESC 12. All such information may be stored in the SSP's 18 customerdatabase (not shown) when the panic button 16 is assigned to aparticular user. Instead of manual database look-up, the SSP 18 mayimplement an automatic database search and comparison process toinstantly identify the operator of the panic button 16 as soon as analarm indication is received from the base unit.

Normally, the carrier network 14 in the panic button application of FIG.2 is a wireline network, e.g., the POTS or the PSTN. However, in asituation involving close monitoring of the elderly or the disabled(e.g., monitoring of patients in a large hospital complex), the panicbutton technology may be employed via a local wireless carrier network14. The patient may activate the personal panic button 16 and thecarrier network 14 may wirelessly transfer the help request toappropriate staff or emergency relief personnel in the hospital's ESC12. The SSP 18 may not be needed in such an environment as symbolicallyindicated by the direct dotted connection between the panic button 16and the ESC 12.

From the foregoing, it can be observed that the prior art devices usedto report emergency conditions (e.g., the telephone 10 in FIG. 1 and thepanic button 16 in FIG. 2) primarily send emergency help requestmessages through telephone signals in a circuit-switched telephoneenvironment, i.e., in a telephone environment that “dedicates” an actualphysical circuit between the caller and the called party. This“traditional” approach to request emergency help by calling ‘911’ maynot be effective sometimes, for example, when the person in need of helpcannot dial the numbers to place a ‘911’ call or when that person cannotorally respond to the questions of an operator receiving the ‘911’ call.Furthermore, the operators or assistants receiving phone calls at theESC 12 may get swamped by a large number of phone calls and may need toput the last caller on hold prior to reviewing the caller's emergencysituation. This may not be desirable, especially when the caller'ssituation demands prompt and instant attention. Additionally, the ESC 12or the SSP 18 may have a finite number of incoming telephone lines. Inthat situation, because of the circuit-switched nature of telephonecommunications, the person placing the emergency call may end upreceiving a line “busy” signal instead of an operator's voice.

The availability of modern high-speed data processors and thecontinually growing popularity of the Internet make it desirable tooffer an emergency reporting device that is capable of reporting auser's need for emergency help using TCP/IP message packets sent overthe Internet to the ESC 12. It is also desirable for the support serviceprovider 18 or a telephone company (telco) to offer a subscription-basedor usage-based emergency reporting service using TCP/IP messaging overthe Internet.

SUMMARY OF THE INVENTION

The present invention contemplates a device for requesting emergencyassistance, comprising a processing unit; a panic button coupled to theprocessing unit, wherein the panic button is configured to send a firstindication to the processing unit when a user of the device activatesthe panic button; and a web browser module coupled to the processingunit, wherein the processing unit is configured to send a secondindication to the web browser module in response to the firstindication, and wherein the web browser module is configured to delivera help request message in a TCP/IP (Transmission ControlProtocol/Internet Protocol) format to an emergency service center (ESC)in response to the second indication.

In one embodiment, the web browser module connects the device to theInternet and sends the help request message to the ESC over theInternet. The device may further include a memory unit to store the helprequest message to be sent to the ESC. The memory may also store variouspersonal information about the user, e.g., the identity of the user, thelocation or address of the user, any known medical condition the user issuffering from, etc. Such additional information may be included by theprocessing unit as part of the help request message sent to the ESC.Furthermore, the user's voice may also be sent to the ESC as one or moreTCP/IP data packets over the Internet.

The panic button may be implemented in hardware or software. In ahardware implementation, the panic button may be provided as a button onthe face of the housing that can be pushed by the user when in need ofemergency help. In a software implementation, a panic button icon may bedisplayed on a touch-sensitive display screen provided on the housing.The user may touch the icon to activate the panic button functionality,i.e., to transmit the help request message to the ESC.

In one embodiment, the device may include a location identifier unitthat supplies the current location of the device (and, hence, of theuser operating the device) to the processing unit to be included as partof the help request message so that ESC personnel may efficiently locatethe user who requested the emergency help. An image capture device mayalso be included to allow the processing unit to transmit to the ESC oneor more images of the physical vicinity of the user when the useractivated the panic button. Such a transmission may help the ESCpersonnel to identify potential cause of the emergency request from theuser and also to obtain evidence that may be needed in future lawenforcement efforts.

The web browser module may include an HTML (Hyper Text Markup Language)browser or a WAP (Wireless Application Protocol) browser. For example,the web browser module may use the HTML browser when accessing theInternet via a PSTN (Public Switched Telephone Network). Alternatively,the web browser module may use the WAP browser when accessing theInternet via a cellular telephone network. Additional wireless datacommunication module may also be provided within the housing to allowthe device to access a wireless communication network.

The device may also include a microphone for the user to orallycommunicate with the ESC. A speaker unit may also be provided to allowthe user to listen to any oral communication. A keypad to enter datatext and a display screen to display the data being entered or text ofany response message received from the ESC may also be included.

The present invention further contemplates a data storage mediumcontaining software to be executed by a device for requesting emergencyassistance, wherein the software is executed by the device uponreceiving an indication therefor from a user requesting emergency help,and wherein, upon execution, the software causes the device to establisha connection with an emergency service center (ESC) via a communicationnetwork; and deliver a help request message in a TCP/IP (TransmissionControl Protocol/Internet Protocol) format to the ESC via thecommunication network.

The storage medium may be, for example, a magnetic storage medium (e.g.,a floppy diskette) or an optical storage medium (e.g., a compact disc).The device may include a storage drive to receive the storage mediumcontaining the emergency assistance software. The software may beexecuted by the user of the device in a number of ways. For example, asmentioned hereinbefore, the user may touch an icon on a touch-sensitivedisplay screen for the device to activate the panic button functionalitysupported by the software.

The present invention still further contemplates a data transferarrangement comprising a device for requesting emergency assistance,wherein the device is operable by a user in need of emergency help; acomputer having stored therein software executable on the device,wherein the device is configured to execute the software in response toan indication therefor received from the user, and wherein the software,upon execution, causes the device to establish a connection with anemergency service center (ESC) via a first communication network, anddeliver a help request message in a TCP/IP (Transmission ControlProtocol/Internet Protocol) format to the ESC via the firstcommunication network; and a second communication network linking thedevice and the computer, wherein the device is configured to transmit adownload request to the computer via the second communication network,and wherein the computer is configured to transmit a copy of thesoftware to the device via the second communication network in responseto the download request from the device. Thus, the panic button softwaremay be downloaded by the device from a remote computer server.

The device according to the present invention advantageously harnessesthe resources of the Internet to allow users to request emergency helpover the Internet by simply pushing a panic button provided on thedevice. Internet-based emergency message delivery may be useful in manysituations, for example, when the person in need of help isspeech-impaired, disabled or in a situation that prevents that personfrom orally requesting emergency help.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 3 shows a schematic of a setup whereby an IP(Internet Protocol)device 20 according to the present invention sends emergency helprequest messages to the emergency service center (ESC) 12 over theInternet 22 or any similar IP-based network. The IP device 20 (describedhereinbelow in more detail) sends the emergency help request via aTCP/IP (Transmission Control Protocol/Internet Protocol) message sentover the Internet 22 to the ESC 12. The carrier network 14 is shownconnecting the IP device 20 to the Internet 22. However, it is knownthat the physical infrastructure (e.g., telephone or cable lines,switches, etc.) of the carrier network 14 may form part of the Internet22. For example, the carrier network may be a wireline telephonenetwork, e.g., the POTS or the PSTN, or may be a combination of awireline and wireless telephone network (e.g., a cellular telephonenetwork). Therefore, the TCP/IP messages sent by the IP device 20 mayshare the same physical network infrastructure with voice communicationtraffic.

It is noted at the outset that, for the sake of convenience and ease ofdescription, the same numerals are used to identify same or similarfunctionality throughout the figures. For example, both the emergencyservice center in FIG. 1 and that in FIG. 3 are identified by numeral‘12’. As in FIG. 1, the ESC 12 in FIG. 3 may represent a police station,a fire station, a hospital, etc. However, the ESC 12 in FIG. 3 mayfurther be equipped to receive and/or transmit TCP/IP messages over theInternet 22. Thus, in some situations, the ESC in FIG. 1 and that inFIG. 3 may not have identical operational hardware and software, butboth of them may perform the same function, i.e., to dispatch emergencyrelief in response to an emergency help request.

The IP device 20 may be connected to the carrier network 14 via aregular telephone line. In one embodiment, a base unit (not shown) forthe IP device 20 may be connected to the telephone line and the IPdevice 20 may be carried on the user's person. Any TCP/IP messagesgenerated by the IP device 20 may be wirelessly transmitted first to thebase unit, which, in turn, may forward them to the carrier network 14using the telephone line. The TCP/IP messages may then be routed to theESC 12 via the Internet 22. In another embodiment, the IP device 20 mayutilize a wireless telephone network (e.g., the TDMA (Time DivisionMultiple Access) cellular network) as the carrier network 14 toinitially transmit TCP/IP message packets to. Thereafter, the wirelessnetwork, in combination with the PSTN and the Internet 22, may route theTCP/IP packets to the ESC 12. In such an event, the carrier network 14may be construed to include the PSTN and the wireless network.

The term “IP device” may be construed to include a number of devicesequipped with panic button and capable of TCP/IP-based datacommunication when the panic button is activated. The panic buttonfunctionality may be accomplished with a hardware panic button (forexample, the panic button 24 in FIG. 4) or a software panic button(described hereinbelow with reference to FIG. 7). The IP devices mayinclude commercially available gadgets such as a wireless pager, acellular telephone, a hand-held computing device (similar, e.g., to aPalmPilot), etc., modified to include the panic button functionality asdescribed hereinbelow. Alternatively, a number of household devices,e.g., an alarm clock or a refrigerator, may be equipped with Internetaccess capability and a panic button to be covered by the term “IPdevice.”

The carrier network 14 may be a wireline communication network, e.g.,the POTS or the PSTN, or an ISDN (Integrated Services Digital Network),or a wired LAN (local area network). Alternatively, the carrier network14 may be a wireless communication network, e.g., an AMPS (AdvancedMobile Phone Service) analog or digital wireless network, a wirelessLAN, a WLL (Wireless Local Loop) or a TDMA (Time Division MultipleAccess) cellular telephone network. The IP device 20 may take a numberof different forms depending, for example, on the carrier network the IPdevice 20 is being used with. For example, in the configuration of FIG.9, the carrier network 14 may be a WLL and the IP device 20 may be awireless handset, or even a cellular phone handset, that transmitsTCP/IP messages over RF (Radio Frequency) channels to the WLL centralswitching facility via a local base station. The central switchingfacility may be managed by the support service provider (SSP) 18. TheSSP 18 may then transmit the received emergency help request messages tothe ESC 12 over the Internet 22.

The IP device 20 may communicate with the ESC 12 using, for example, theinstant messaging functionality supported by an IP-based network, e.g.,the Internet 22. The instant messaging feature allows the IP device 20to establish a direct session or a virtual connection with the remoteESC 12 via the Internet 22. In one embodiment, the IP-based network(here, the Internet 22), and preferably the carrier network 14 as well,may employ “classes of service” or “quality of service” classificationschemes for data packets handled by the network. Some parameters thataffect a network's classification scheme include, for example, the databandwidth required, the latency to be tolerated during a messagetransmission and the acceptable error-rate during a messagetransmission. For example, in the case of routine e-mail or “chat”messages, more latency may be tolerated. However, the IP-based networkmay establish that certain emergency messages (e.g., messagesoriginating from the IP device 20) or other messages (e.g., videoconferencing data) requiring instant transmission of the message withoutdelay may be assigned the highest priority or “class of service” whenthe IP network has to allocate its data transmission bandwidth among thecompeting data packets.

FIG. 4 is an illustration of an embodiment of the IP device 20 of thepresent invention wherein the IP device 20 has a physically built-inpanic button 24. The IP device 20 may be a portable or wearable unit.Alternatively, the IP device 20 may be a normally non-moving or fixedunit such as, for example, a household appliance (e.g., a refrigeratoror an alarm clock) that is equipped with, for example, a web browser toaccess the Internet as described hereinbelow. When the IP device 20 isportable, it may have an associated base unit (not shown) to transmitappropriate signals to the carrier network 14. For example, the IPdevice 20 may communicate wirelessly with its corresponding base unitand the base unit may be physically connected to a telephone line toforward messages received from the IP unit 20 to the carrier network 14,which, here, may be the PSTN. The panic button 24 is shown installed ina housing 26, which additionally includes a display screen (or“display”) 28, a keypad or keyboard 30, a speaker 32 and a microphone34. In the case of a hand-held, portable IP device 20, the housing 26may be built of relatively hard and unbreakable plastic or ashock-resistant ABS (Acrylonitrile Butadiene Styrene) material so thatto allow a user, for example, to carry around the IP device 20 onhis/her person. The electronic circuit blocks within the housing 26 aredescribed hereinbelow with reference to FIG. 6. The housing 26 mayinclude a source of electrical power (e.g., a storage battery) toprovide requisite power to various circuit elements therein.

The panic button or the help button 24 may be provided on the housing 26in a number of different ways. For example, in one embodiment, the panicbutton 24 may be a push-button or a key similar to a key on a computerkeyboard. However, in another embodiment, the panic button 24 may be amembrane key. Similarly, the keys or “buttons” on the keypad 30 may beprovided as, for example, push-button keys or computer keyboard-typekeys or membrane keys or any other suitable design configuration. Thechoice of the type of panic button 24 and the type of keys on the keypad30 may thus depend on design and aesthetic considerations including, forexample, the size, the weight and the desired physical contours for theIP device 20. The user of the IP device 20 may need to push the panicbutton 24 only once to transmit the emergency request message in theTCP/IP form.

The display screen 28 may display text or graphic messages thereon. Forexample, when the IP device 20 functions as a pager, the display screen28 may function as a routine display available on a paging device todisplay the messages received by the IP device 20. In one embodiment,the display screen 28 may be an LCD (liquid crystal display) display. Inalternative embodiments, the display screen may be a TFT (thin filmtransistor) active matrix display or a touch-sensitive screen. Atouch-sensitive display screen may be useful when the panic buttonfunctionality is implemented in software as discussed hereinbelow withreference to FIG. 7. In that case, the user of the IP device 20 maysimply touch an emergency help or panic button icon provided on thedisplay screen 28 to activate the software panic button to transmit theemergency help request message.

As depicted in FIG. 4, the housing 26 may include built therein aspeaker 32 and a microphone 34. In one embodiment, after invoking theemergency help functionality by pressing the panic button 24, the userof the IP device 20 may additionally speak into the microphone 34. TheIP device 20 may be configured to transmit the user's voice over theInternet and to the ESC 12 by using known voice-over-IP methods. Theuser may also be able to listen to voice responses from the operator atthe ESC 12 via the speaker 32. These voice responses may be transmittedover the Internet. Alternatively, if the IP device 20 is physicallyconnected to a telephone line (e.g., a PSTN line), the ESC 12 may takecontrol of that telephone line (if already busy) or may place atelephone call to the IP device 20 over that telephone line once the ESC12 receives the emergency help request message from the IP device 20over the Internet. The user of the IP device 20 may then be able toorally communicate with an operator at the ESC 12 via the speaker 32 andthe microphone 34.

FIG. 5 illustrates another embodiment of the IP device 20 having abuilt-in digital camera or other image capture device 36. A miniaturedigital camera 36 may be built into the housing 26 to take quicksnapshots, or motion pictures, of the environment surrounding the userof the IP device 20. The camera 36 may be activated when the panicbutton 24 is pressed by the user and the camera 36 may remain activatedfor a predetermined time thereafter (e.g., for 30-60 seconds) prior toautomatically shutting off itself. The camera lens may rotate within thehousing 26 to “cover” a circular view angle of (or approximately) 360°.The video information provided by images shot by the camera 36 may behelpful in, for example, medical treatment of the user of the IP device20, in law enforcement (e.g., when the user activates the panic button24 in response to a burglary attempt or in response to a threat to theuser's physical safety), etc.

The images captured by the digital camera 36 may be transmitted asTCP/IP data packets to the ESC 12 upon activation of the panic button24. These images may also remain stored in a memory provided within thehousing 26 so as to enable security or health personnel to retrieve theimages at a later time, for example, by “downloading” the digital imagefiles onto a computer. The images captured by the digital camera 36 maybe stored and transmitted as digital data files having a predefined fileformat including, for example, the GIF (Graphics Interchange Format)format, the TIFF (Tag Image File Format) format, the JPEG (JointPhotographic Experts Group) format, the MPEG (Motion Picture ExpertsGroup) format, or any other desirable format. Except for the addition ofthe digital camera 36, the IP device 20 in FIG. 5 is identical to thatin FIG. 4.

FIG. 6 depicts an exemplary block diagram of constituent circuit blocksin an embodiment of the IP device 20 of the present invention. Thecircuit elements that may be placed within the housing 26 include anetwork interface unit (NIU) 38, an audio logic unit 40, a display logicunit 42, a keypad interface logic unit 44, a memory or storage unit 46,a DTMF (Dual Tone Multi Frequency) dialer 48 and a web browser module50. These circuit elements are shown coupled to a processing and controlunit (PCU) 52 that manages and controls various operations performed bythese circuit elements. The NIU 38 may include a modem 54 so as toenable the web browser module 50 to transmit and receive digitalinformation over a telephone or an ISDN line and to thereby access theInternet. It is noted that all of the circuit elements shown in FIG. 6need not be included in one housing (e.g., the housing 26). In otherwords, one or more of the circuit elements shown in FIG. 6 may remainoutside of the housing 26. For example, in one embodiment, the displaylogic unit 42 and the display 28 may not be part of the housing 26. Inthat embodiment, the housing 26 may be electrically connected (e.g., viaa corded, or a cordless or wireless connection) with a remotely locateddisplay logic unit 42 and its corresponding display 28.

The network interface unit 38 provides an electrical interface forsignals travelling between various circuit elements inside the housing22 and a wireline carrier network, e.g., the carrier network 14 in FIG.3, connected to the IP device 20 either directly or via a base unit (notshown) associated with the IP device 20 as discussed hereinbefore.Different signals, such as a dial tone received over a telephone line inthe carrier network 14, digits dialed by the DTMF dialer 48, datacommunication signals (including the TCP/IP emergency request messages)transmitted and/or received by the web browser module 50, etc., may passthrough the NIU 38 prior to reaching their appropriate destinations. TheNIU 38 may provide signal amplification, for example, in a noisy signalenvironment. The NIU 38 may also include circuitry for the modem 54 tofacilitate data communication for the web browser module 50 over, forexample, a telephone line or an ISDN line.

The audio logic unit 40 may be connected to the microphone 34 and thespeaker 32. The speaker 32 may be activated by the audio logic unit 40when the PCU 52 informs the audio logic unit 40 that the panic button 24has been pushed. Voice messages sent by, for example, the servicepersonnel at the ESC 12, may first be received by the PCU 52 (via theNIU 38) and the PCU 52 may transmit these signals to the audio logicunit 40 to be sent to the speaker 32 for generating audible sound.Alternatively, any digital audio files received by the IP device 20(using the NIU 38) over the Internet 22 may first be sent to the webbrowser module 50 to retrieve the audio file data therefrom. The browsermodule 50 may then send the audio data to the PCU 52, which, in turn,forwards the audio data to the audio logic unit 40 and eventually to thespeaker 32. The ESC 12 may be configured to automatically transmitpre-recorded audio information over the Internet 22 (via TCP/IP messagepackets) when the ESC 12 receives an emergency request message from theIP device 20.

The user of the IP device 20 may speak into the microphone 34 totransmit the user's voice over the Internet 22. The audio logic unit 40receives the electrical audio signals from the microphone 34 and sendsthem to the PCU 52, which, in conjunction with the browser module 50,transmits the user's voice over the Internet 22 using the NIU 38. In oneembodiment, the user may store the user's personal identificationinformation as a digital audio file in the memory unit 46 by speakinginto the microphone 34. The PCU 52 may convert the audio electricalsignals received from the audio logic unit 40 into the predetermineddigital audio file format and store the user's personal information inthe memory unit 46. The personal information may include the user'sname, address, any known medical condition, contact information in caseof emergency, etc. The digital audio file formats for the user'spersonal information may include file extensions such as, for example,“.WAV” (wave file), “.AIFF”(Audio Interchange File Format), “.AU”(audiofile), etc. Upon activation of the panic button 24, the PCU 52 mayretrieve the personal information from the memory 46 and may transmit itto the web browser module 50, which, in turn, may immediately send theinformation to the ESC 12 via TCP/IP packets sent over the Internet 22.

The display logic unit 42 monitors and manages display functionality forthe IP device 20. The PCU 52 may generate proper commands and signalsfor the display logic unit 42, which, in turn, may control the displayof visual information on the display screen 28. The display screen 28may display various information such as, for example, an e-mail messagereceived from the ESC 12 or any data entered via the keypad 30 or anintimation of which action is being performed by the IP device 20. Forexample, the browser module 50 may instruct the DTMF dialer 48 (via thePCU 52) to start dialing the telephone number for Internet access. Oncethe DTMF dialer 48 starts dialing that access number, the PCU 52 mayinstruct the display logic unit 42 to display a phrase such as “DIALINGIN PROGRESS” on the visual display screen 28. Similarly, a message suchas “ACCESSING THE INTERNET” may also be sent to the display logic unit42 (to be displayed on the display screen 28) by the PCU 52 once the PCU52 receives an indication from the web browser module 50 that Internetaccess is in progress. Other messages may also be conveniently displayedon the screen 28. For example, as soon as the user presses a key on thekeypad 30, the corresponding digit, symbol or command may be displayedon the display screen 28 by the display logic 42.

The keypad interface logic 44 is coupled to the keyboard 30 and receivessignals sent from the keyboard 30 when the user presses one or more keysthereon. The user may “program” the IP device 20 with pertinent dataabout the ESC 12 including, for example, the name of the ESC 12, the IPaddress of the ESC 12, the telephone number and name of the contactperson at the ESC 12, the e-mail address of the ESC 12, etc. These datamay be entered using various keys on the keypad 30. The web browsermodule 50 may need a portion of such data to determine how to access theESC 12 over the Internet 22. Furthermore, the user may also prefer toenter personal information about the user, e.g., the user's name, theaddress of the user's contact location, any known medical condition,name and contact information about the user's family physician, etc.

The keypad interface 44 transmits the signals received from the keyboard30 to the PCU 52 for further processing. The PCU 52 decodes the receivedsignals and accordingly instructs the appropriate circuit elements fornecessary action. For example, when the user enters the user's personalinformation and the data pertaining to the ESC 12, the keypad interfacelogic 44 may send all the data to the PCU 52, which may instruct thememory unit 46 to store the received data therein. The PCU 52 may storethe user's identification information, the ESC 12 access data, etc., inthe memory 46 using one of a number of digital text formats, e.g., HTML(Hyper Text Markup Language) format, ASCII (American Standard Code forInformation Interchange) format, XML (Extensible Markup Language) textfile format developed by W3C (World Wide Web Consortium), etc.

In one embodiment, the housing 26 may include a text-to-speech (TTS)converter (not shown). The TTS conversion functionality may beimplemented with appropriate software residing in the PCU 52. The TTSconverter may work with an SGML (Standard Generalized Markup Language)format-based TTS markup language. The SGML format may be based on theASCII text format. An example of an SGML-based TTS markup languageincludes the STML (Spoken Text Markup Language) developed by LucentTechnologies of Murray Hill, N.J., USA. In that embodiment, the ESC 12may be configured to transmit to the IP device 20 an e-mail or otherresponse message over the Internet 22 using the SGML format. Such aresponse message may be generated when the ESC 12 receives the emergencyrequest message from the IP device 20. The response e-mail from the ESC12 may state in general terms that the ESC 12 has received the helprequest message and the requested help is being dispatched. This schemeallows for a quick “confirmation” of receipt of the help request messagefrom the IP device 20 and also for an expedited “response” back to theIP device 20 to pacify and comfort the user of the IP device 20 prior tothe arrival of emergency personnel. The TTS converter may convert thetext file received from the ESC 12 into an STML file that can be audiblyplayed back by the audio logic unit 40. The user of the IP device 20 canthus hear, in a synthesized voice, the content of the message sent bythe ESC 12 in a digital text format.

The memory or storage unit 46 provides memory for storage of data, suchas the user's personal information as discussed hereinbefore. The datastored locally in the memory unit 46 may be text, audio or video dataand may include a number of digital file formats as describedhereinbefore. For example, data that may be sent over the Internet 22may be in the HTML or the WML (Wireless Markup Language) formatsdepending on whether the web browser module 50 is used with a wirelinecarrier network or a wireless carrier network respectively as describedhereinbelow. The memory unit 46 may be located inside the housing 26 or,alternatively, may be supplied as a memory cartridge (not shown) thatmay be attached to the housing 26 at an appropriate adapter slot (notshown) provided on the housing 26.

The memory unit 46 may include volatile and/or non-volatile memory, suchas RAM (Random Access Memory), ROM (Read Only Memory), EEPROM(Electrically Erasable Programmable Read Only Memory), flash memory, orother similar memory units. A volatile memory may lose the data storedtherein if the power applied thereto is removed. The personalinformation about the user (as an audio file or as a text file) as wellas the contact information about the ESC 12 may be stored in thenon-volatile portion of the memory 46. On the other hand, a pagingmessage may be stored in the volatile portion (or temporary storage) ofthe memory 46 for an IP device 20 that may also function as a wirelesspager.

In one embodiment, the DTMF (Dual Tone Multi Frequency) dialer 48communicates with the PCU 52 and receives the telephone number sent tothe PCU 52 by the web browser module 50 for dial-in Internet access. Thetelephone number may be for direct access to the ESC 12 or it may be foran ISP (Internet Service Provide) through which the emergency requestmessage may be sent to the ESC 12 over the Internet 22. The DTMF dialer48, in turn, generates corresponding DTMF signals to be sent to thelocal telephone switching office in the carrier network 14 via the NIU38. The DTMF signals may be sent over a telephone line either directlyfrom the IP device 20 or from a corresponding base unit (not shown) forthe IP device 20 as discussed hereinbefore.

The web browser module 50 may include software code or routines which,when executed by the PCU 52, perform web browser functions uponexecution. In one embodiment, the web browser module 50 may beimplemented using a combination of software and hardware elements. Theweb browser software may include, for example, an HTML browser or a WAP(Wireless Application Protocol) browser because of the small size andportable nature of the IP device 20 and because of the smaller display28 and limited memory space (in the memory unit 46) available for the IPdevice 20. A commercially available HTML browser, for example, theNetscape Navigator™ or the Microsoft Internet Explorer™ m may beselected for the web browser module 50. In case of a WAP browser, acommercially available WAP-compliant microbrowser (or wireless webbrowser) used, for example, in Nokia™ 7100 series cell phone or in thePalm Pilot™ hand-held computer versions 5.0 or 6.0 may be selected. TheHTML browser may “read” information received or stored in the HTMLformat, whereas the WAP browser may be able to “read” information havingWAP content (e.g., information in the WML (Wireless Mark-up Language)format). The web browser software, upon execution, may access a physicalcommunication medium (e.g., a telephone line) in the carrier network 14using the modem 54 and may dial into an ISP (Internet Service Provider)server (not shown). The ISP server thus allows the web browser module 50to connect to the Internet 22.

The web browser 50 may be activated using one or more keys on the keypad30 and may be used for surfing the world wide web portion of theInternet. Furthermore, the web browser module 50 may also beautomatically activated once the panic button 24 is pressed by the userof the IP device 20. In that case, the web browser 50 may retrieve (viathe PCU 52) relevant locally-stored information (e.g., the web addressof the ESC 12 or the personal information about the user) from thememory unit 46 and transmit an appropriate portion of that informationover the Internet 22 in response to the activation of the panic button24. The web browser module 50 interacts with the PCU 52 to executenecessary software routines for Internet access. The software routines,upon execution, activate the modem 54 in the NIU 38 to establish anelectrical connection with a wireline carrier network (e.g., via atelephone line (not shown)) to accomplish dialed Internet access. In oneembodiment, the web browser module 50 (including its hardware and/orsoftware elements) may be a part of the PCU 52 and the PCU 52 maydirectly perform web browsing or information delivery over the Internet22.

Inclusion of the web browser 50 within the IP device 20 results in astandardized information interface for the IP device 20 because itdispenses with the need to have a proprietary format for informationtransmission, storage and display. The emergency help request messagesdoes not have to be in a proprietary format for the ESC 12 to be able toread them, but, instead, the messages to and from the ESC 12 may be in agenerally available text format, e.g., the HTML format or the WMLformat. This allows for ease of communication between the user and theESC 12 using TCP/IP data packets over the Internet 22.

The PCU 52 manages and controls various operations performed bydifferent circuit elements connected thereto. The PCU 52 functions as acentralized location to send and receive various commands andinformation. For example, the PCU 52 may receive a signal from the panicbutton 24 when the user activates the panic button 24. In response, thePCU 52 may execute the web browser software in the browser module 50 toinitiate an Internet connection. The PCU 52 may receive a responsivemessage, e.g., in an e-mail format, from the ESC 12 (via the browsermodule 50) and may, in turn, instruct the display logic 42 to displaythe message on the display screen 28. Alternatively, the PCU 52 mayinstruct the TTS converter (not shown) to audibly “play” the messagetext using the audio logic unit 40 and the speaker 32 as describedhereinbefore. During web browsing, the PCU 52 may also execute audio andvideo data files received from the Internet 22 using the web browsermodule 50 and send appropriate audio and video signals to the audiologic unit 40 and the display logic unit 42 respectively.

In one embodiment, the PCU 52 may time-stamp each outgoing TCP/IPmessage in response to the activation of the panic button 24. Thus, thetime when the emergency arose may be accurately traced by looking at thereceived emergency help request message at the ESC 12 (or at the SSP 18in FIG. 8). This may be of help to the ESC 12 in organizing itsemergency help efforts. Some exemplary PCUs include the Intel x86 seriesmicroprocessors or the Motorola 68x series microprocessors.

The modem 54 may be used to transmit and receive digital data over awireline carrier network 14, e.g., the PSTN or the ISDN. The modem 54modulates and demodulates the digital information transmitted andreceived respectively over a physical communication medium, e.g., a PSTNtelephone line or an ISDN line. The modem 54 may employ one or more of anumber of modulation schemes including, for example, FSK (frequencyshift keying), DPSK (differential phase shift keying), QAM (quadratureamplitude modulation) and TCM (trellis-coded modulation). The modem 54may function in a full duplex communication mode allowing simultaneoustransmission and reception of electrical signals. The modem 54 mayperform error correction for transmitted and received data. The datacommunication speed of the modem 54 may be, for example, 56 kbps (kilobits per second) with automatic fall-back capability in the event ofnoisy line conditions or due to a mismatch between the datacommunication speeds of the modem 54 and the device with which the modem54 is communicating. Any Hayes® compatible modem may be used for themodem 54.

The IP device 20 may include a number of optional circuit elementswithin the housing 26 as indicated by dotted boxes in FIG. 6. Oneoptional circuit element is the digital camera or image capture device36 discussed hereinbefore with reference to FIG. 5. The image capturedevice 36 is shown connected to the panic button 24 to allow for instantactivation of the image capture device 36 in response to the activationof the panic button 24. Some additional optional circuit elements mayinclude a voice recognition unit 56; a sensing device or a sensor 58; auser location identifier 59 including a GPS (Global Positioning System)receiver 60 and a GPS receiver antenna 62; and a wireless datacommunication module 64 including a wireless modem 66, an RF (RadioFrequency) transceiver unit 68 and an RF antenna unit 70.

The voice recognition unit (VRU) 56 is connected to the microphone 34 toreceive speech and other audio signals captured by the microphone 34.The voice recognition functionality may be implemented with hardwareand/or software components in the VRU 56. The VRU 56 may be programmedto identify and recognize the voice of the user of the IP device 20.Furthermore, the VRU 56 may be configured to recognize specificfrequencies in the user's voice and, upon such recognition, may conveyappropriate message to the PCU 52 informing the PCU 52 to activate theweb browser module 50 and to transmit an emergency help request messageto the ESC 12 over the Internet 22. For example, the VRU 56 mayrecognize only a shrill or a high-pitched voice pattern generated whenthe user of the IP device 20 senses danger (e.g., a burglary attempt oran actual or impending physical assault on the user) or is in need ofemergency help. Such an arrangement may be necessary to avoid falsetransmission of emergency help request messages (or “false alarms”) tothe ESC 12. For example, if the VRU 56 is mistakenly configured toactivate the emergency help request feature (via the PCU 52) wheneverthe VRU 56 recognizes the user's voice (e.g., when the user performsnormal conversation), this may cause undesirable transmissions of helprequest messages to the ESC 12. This may be subversive to the purpose ofthe emergency help request feature and may damage the credibility of theuser as a person in need of emergency help.

In one embodiment, the VRU 56 may also have speech recognitioncapability to identify the words spoken by the user in distress. The VRU56 may then send those recognized words as a digital text file to thePCU 52, which, in turn, may transmit the digital text file along withany other emergency help request message text to the ESC 12. This mayinform the ESC 12 of what was spoken by the user immediately prior torequesting emergency help and may also allow the ESC 12 to commenceappropriate relief efforts in response. For example, in addition todispatching medical workers, the ESC 12 may also dispatch fire fightersif the user's spoken words indicate that the user is caught in a fire.

The sensor or the sensing device 58 may sense a physical conditionafflicting the user of the IP device 20. For example, if the user is aheart patient, the sensor 58 may continuously monitor the user'sheartbeats to identify any abnormality therein. Upon detecting anabnormal condition, the sensor 58 may trigger the panic button 24,which, in turn, may inform the PCU 52 to transmit (using the web browsermodule 50) an emergency relief request message to the ESC 12. In analternative embodiment, the output of the sensor 58 may be connecteddirectly to the PCU 52 instead of through the panic button 24. Thesensor 58 may be configured to sense other emergency conditions as well.For example, the sensor 58 may sense abnormal blood pressure levels orunusual body temperature. In one embodiment, the sensor 58 may containcircuitry to detect specific frequencies contained in the sound of abreaking glass to immediately inform the ESC 12 (via automaticactivation of the panic button 24) of any burglary attempt at the user'shousehold.

The user location identifier 59 within the housing 26 is shown toinclude a GPS receiver 60 and a GPS receiver antenna 62. The GPSreceiver antenna 62 may be provided on the housing 26 to continuouslyreceive location signals from geostationary satellites and transferthose signals to the GPS receiver 60 to identify the current location ofthe IP device 20 and, hence, of the user carrying the IP device 20.Instead of a built-in location identifier 59, the housing 26 may beprovided with a port (not shown) to receive an external locationidentifier (with or without the receiver antenna 62) that may beattached to the port when needed. The GPS location identifier 59 mayperform better in an outdoor environment. This may be useful when theuser is on the road or at a remote location where access to a telephonemay not be easily available. In that case, the user's location may betransmitted along with the emergency help request message to the ESC 12.The user location identifier 59 may supply the PCU 52 with the requisitelocation information and the PCU 52, with the help of an appropriate webbrowser module 50 and the wireless data communication module 64(described hereinbelow), may send the emergency help request messagealong with the user location information over the Internet 22 to the ESC12. The commercially available Megellan GPS receiver may be included aspart of the user location identifier 59.

The wireless data communication module 64 employs wireless devices totransfer data and information between the IP device 20 and the ESC 12over the Internet 22. An antenna, e.g., an RF (radio frequency) antenna70, may be provided on the housing 26 of the butt set 74 to allowwireless data communication. In the event of wireless datacommunication, the NIU 38 (including the wireline data modem, i.e., themodem 54) may remain inactive. Furthermore, when the IP device 20 isequipped with cellular telephone features or paging device features, thehousing 26 for that IP device 20 may include only the wireless datacommunication module 64 and may omit the NIU 38. Here, datacommunication may be accomplished via a wireless modem 66 using awireless carrier network 14. If the wireless carrier network 14 is acellular network (e.g., a TDMA-based wireless network or a CDMA-based(Code Division Multiple Access) wireless network, or a GSM-based (GlobalSystem for Mobile Communications) wireless network), then the wirelessmodem 66 may be capable of data transfer using the message formatsupported by the given cellular network.

The web browser module 50 in the housing 26 may be configured totransfer data over a wireless carrier network 14 and, hence, the webbrowser module 50 may be connected to the wireless modem 66. The webbrowser module 50 may include a WAP (Wireless Application Protocol)browser to access the Internet 22. The WAP browser in the web browsermodule 50 may transfer data over the Internet 22 using a WAP-supporteddata format, e.g., the WML (Wireless Markup Language) format. In oneembodiment, the web browser module 50 may be configured to responsivelyconnect to a wireline data modem (e.g., the modem 54) or a (wirelessmodem 66 depending on the desired mode of data communication. A webbrowser module 50 with an HTML browser may be similarly configured toperform data transmission and reception operations using wirelessdevices (similar to, for example, the wireless data communication module64). The IP device 20 may also include a web browser module 50 withbrowser software that supports a content format that is different fromHTML or WML such as, for example, the JavaScript scripting language. AnIP device may be conveniently designed to include such a web browsermodule for data communication.

The RF transceiver unit 68 sends RF signals to the RF antenna 70 fortransmission to the wireless carrier network 14 and receives RF signalsfrom the RF antenna 70 and forwards them to the wireless modem 66 forfurther processing. The RF antenna 70 provides the necessary signalinginterface between a wireless carrier network 14 and the web browsermodule 50 that needs to access the wireless network 14.

The wireless carrier network 14 may be, for example, an analog wirelessnetwork (e.g., the AMPS (Advanced Mobile Phone System) network), adigital wireless network including cellular networks (e.g., the TDMA orCDMA-based wireless networks), a wireless LAN (Local Area Network) or aWLL (Wireless Local Loop) configuration. A portion of the wirelesscarrier network 14 may include one or more microwave links forsatellite-based communication. A WAP proxy/server (not shown) may beincluded as part of the wireless carrier network 14 to facilitate accessto the Internet 22 using a wireless IP device 20 (e.g., a cellulartelephone equipped with the panic button 24).

The wireless modem 66 may perform necessary data encoding for the datareceived from the WAP browser in the web browser module 50 to preparethe data (e.g., an emergency help request message) to be sent to thewireless carrier network 14 and eventually to the ESC 12 over theInternet 22. A corresponding decoding may be performed by the wirelessmodem 66 upon receipt of data (e.g., a confirmation message from the ESC12) from the RF transceiver unit 68 prior to sending the decoded data tothe WAP browser (in the web browser module 50) for further processing.The Ricochet SE wireless modem manufactured by Metricom, Inc. of LosGatos, Calif., USA or a wireless modem manufactured by US Robotics maybe selected for the wireless modem 66.

The RF transceiver unit 68 modulates data received from the wirelessmodem 66 to be transmitted over an RF transmission channel linking thehousing 26 with the wireless carrier network 14. This modulated data isthen wirelessly transmitted to the carrier network 14 (and, hence, tothe Internet 22) by the RF antenna unit 70. Upon reception of any dataor information from the wireless carrier network 14 (e.g., an Internete-mail message received from the ESC 12 over the Internet 22), the RFantenna unit 70 forwards the RF-modulated data to the RF transceiverunit 68, which demodulates the data and sends it to the wireless modem66 for further processing and transfer to the WAP browser in the webbrowser module 50.

FIG. 7 shows two ways of downloading emergency reporting software in anembodiment of the IP device 20 according to the present invention andimplementing the panic button functionality through software. In oneembodiment, the support service provider (SSP) 18 (FIGS. 2, 8 and 9) mayoperate a computer server 72 or any other remote data supplying devicethat may download the requisite emergency reporting software onto the IPdevice 20 via a communication network (here, the Internet 22). In otherwords, the IP device 20 may first access the SSP server 72 via theInternet 22 and thereafter activate the software download process. Inalternative arrangements, the communication network linking the IPdevice 20 and the SSP server 72 may include (in addition to or in placeof the Internet 22) a local area network (LAN), a wide area network(WAN), a wireless communication network (e.g., the cellular telephonenetwork), or a combination of one or more of these networks. The supportservice provider 18 is an entity (commercial or non-commercial) that mayoperate independently of the ESC 12. The SSP 18 may distribute the IPdevice 20 and may provide special access to the SSP server 72 or otherSSP-supported services for SSP's subscribers. Additional discussionabout SSP 18 is given hereinbelow with reference to FIGS. 8 and 9.

In another embodiment, the IP device 20 may be provided with one or morebuilt-in hardware storage drives, e.g., a floppy disk drive or a compactdisc drive (not shown). Alternatively, the housing 26 may include acommunication port (e.g., a serial communication port) (not shown) towhich an external storage drive may be attached to transfer data intothe memory 46 within the housing 26. A floppy disk 74 or a compact disc76 or any other storage medium (e.g., magnetic or optical) containingthe requisite emergency reporting software may be provided by the SSP 18to the user/purchaser of the IP device 20 to be inserted into thecorresponding storage drive to download the software into the memory 46.

The emergency reporting software (ERS) is application software that maysimulate the functionality of the hardware panic button 24 in software.Thus, the hardware circuitry associated with the panic button 24 may beeliminated. Instead, the emergency reporting software may get executed(by the PCU 52) whenever the user pressed the panic button 24 on theface of the housing 26. The execution of the ERS may result inactivation of the web browser module 50 to perform necessary datatransmission (e.g., transmission of the emergency help request messageto the ESC 12) over the Internet 22. In an alternative embodiment, ahardware panic button 24 may not be provided on the face of the housing26. Instead, the display screen 28 may be made touch-sensitive and theERS may permanently display an icon (not shown) on the display screen 28identifying the panic button 28. The user may simply touch the icon onthe display screen 28 and, in response, the PCU 52 may execute the ERSto send the emergency help request message to the ESC 12 over theInternet 22.

FIG. 8 illustrates an arrangement showing how the support serviceprovider (SSP) 18 forwards an emergency help request message from the IPdevice 20 to the emergency service center 12. The SSP 18 acts as anintermediary that first receives the emergency requesting message fromthe IP device 20 over the Internet 22. Thereafter, the SSP 18 mayforward that message to the ESC 12 or may itself contact the ESC 12 onbehalf of the user of the IP device 20. The SSP 18 may also explain thepotential problem to ESC 12 personnel based on any information containedin the message received from the IP device 20 or based on anyearlier-stored information about the user when the user first subscribedto the SSP's service.

As noted before, the SSP 18 may provide subscription-based emergencyassistance service or, alternatively, the SSP 18 may be a not-for-profitorganization offering help to a class of citizens, e.g., the elderly.The SSP 18 may sell, rent or offer for free the IP devices 20 to itssubscribers. The SSP 18 may also maintain a database of all of itssubscribers with relevant information about them, e.g., known medicalconditions, an emergency contact address, a home address, etc. The SSP18 may thus act as a link between the user of the IP device 20 and theservice personnel at the ESC 12 who may need certain information aboutthe user prior to recommending appropriate emergency relief.

The connection between the IP device 20 and the SSP 18 via a carriernetwork A 78 and the Internet 22 is similar to the arrangement describedhereinbefore with reference to FIG. 3. In FIG. 8, the carrier network A78 may be identical to the carrier network 14 (FIG. 3) and the recipientof the message, i.e., the SSP 18 may be analogized with the ESC 12 inFIG. 3. Therefore, in view of the discussion given hereinbefore,additional discussion of message delivery operation from the IP device20 to the SSP 18 is not provided herein.

The SSP 18 is shown connected to the ESC 12 via a carrier network B 80.The carrier network B 80 may be a part of the carrier network A 78. Forexample, both the carrier network A 78 and carrier network B 80 may bepublic switched telephone networks. However, the telephone number dialedby the IP device 20 to deliver an emergency message to the SSP 18 viathe carrier network A 78 (and also via the Internet 22) may be differentfrom the telephone number dialed by the SSP 18 to inform the ESC 12 (viacarrier network B 80) of the user's emergency need. It is noted that thediscussion given hereinbefore with respect to carrier network 14 appliesequally to one or both of the carrier network A 78 and carrier network B80. For example, carrier network B 80 may be a wireless carrier network(e.g., a cellular phone network) whereas the carrier network A 78 may bea wireline carrier network (e.g., the PSTN).

In one embodiment, the carrier network B 80 may also include theInternet 22. In other words, the SSP 18 may first receive the emergencyhelp request message from the IP device 20 and may, in turn, forwardthat message (with or without additional information) to the ESC 12 overthe Internet 22 (i.e., via the carrier network B 80). This may behelpful to prevent confusion and flooding of TCP/IP messages at the ESC12 when different users directly contact the ESC 12. Instead, the SSP 18may function like a “hub” that receives messages from all of itssubscribers and then forwards them to the ESC 12. The ESC 12 may thusdeal with only one entity, i.e., the SSP 18. Further, the ESC 12 mayprovide the SSP 18 with a special access code or identification numberto indicate (to the personnel at ESC 12) that the messages are from thesubscribers of the SSP 18. The ESC 12 may then, if needed, inquirefurther with the SSP 18 (regarding the nature or severity of theemergency condition) prior to dispatching emergency help.

FIG. 9 depicts an alternative arrangement whereby the support serviceprovider 18 delivers the emergency help request message received from anemergency reporting device (ERD) 82 to the emergency service center 12over the Internet 22. Here, the SSP 18 first receives the emergency helprequest message via the carrier network 14 that does not include theInternet 22. In other words, the emergency help request from the ERD 82may not be in the form of a TCP/IP message. Instead, the SSP 18 may“convert” the receive non-TCP/IP message into a TCP/IP message to besent to the ESC 12 over the Internet 22. The SSP 18 may optionallytime-stamp the TCP/IP message prior to sending the message to the ESC 12to indicate the time the emergency was reported. The time-stamping bythe SSP 18 may be based on the time-stamp, if provided, in the originalmessage received from the ERD 82.

In the method of message delivery illustrated in FIG. 9, the ERD 82 mayinclude an IP device or a non-IP device, with or without a built-inpanic button (in hardware or software implementations). In other words,the ERD 82 may include, for example, a regular desktop telephone or acellular telephone (not shown). Even the IP device 20 may qualify as anERD 82 when, for example, the IP device 20 sends a non-TCP/IP emergencyhelp request message (e.g., a regular voice message over a telephonecall) to the SSP 18. The user of the ERD 82 may explain the emergencysituation to an operator at the SSP 18 or, alternatively, the user ofthe ERD 82 may simply press a panic button provided on the ERD 82 toidentify the user as the person in need of emergency help. In the lattersituation, the SSP 18 may obtain more information about the user bysimply consulting its subscriber database that may contain the user'spersonal, medical and contact information as discussed hereinbefore.

Once the SSP 18 receives a live message or an indication (e.g., when apanic button is pushed) from the user of the ERD 82 that the user needsemergency help, the SSP 18 (i.e., an operator at the SSP 18) may send anemergency help request message to the ESC 12 over the Internet 22. Themessage from the SSP 18 may be pre-formatted and may also include text(obtained from searching the subscriber-database maintained by the SSP18) containing additional personal information about the user to assistESC 12 personnel in providing emergency help to the user.

In the arrangements of FIGS. 8 and 9, the SSP 18, as part of theemergency help request message to the ESC 12, may include informationabout the identity of the user (e.g., the name of the user or otherphysical mark or identification of the user), the location of the user(i.e., the address of record with the SSP 18 or the address where theemergency service is to be sent), medical information about the user(e.g., prior known medical conditions or allergies), the time when theuser requested help and an indication of a probable cause of the user'sdistress (e.g., illness, injury, fire, etc.) in the message. As notedhereinbefore, part or all of such user-specific information may bealready present in the emergency message received from the IP device 20.In one embodiment, the SSP 18 may add any missing and relevantuser-specific information prior to sending the emergency requestingmessage to the ESC 12.

The carrier network 14, as described hereinbefore, may be a wirelinenetwork or a wireless network or a combination of both. Thus, themessage received at the SSP 18 may not be in the TCP/IP format. However,the SSP 18 may “convert” the received message into a TCP/IP message tofacilitate its transmission over the Internet 22. The SSP 18 may chargea nominal amount (e.g., one dollar) per emergency help request from auser. Alternatively, the SSP 18 may charge a flat sum of money assubscription fees for a user to avail of SSP's emergency assistantservices.

An advantage of the message transfer arrangements illustrated in FIGS. 8and 9 is that the user or operator of the ERD 82 (which may include theIP device 20 as mentioned hereinbefore) need not worry about theidentity or contact information about the ESC 12. The SSP 18 coordinatesthe emergency help on behalf of the user—i.e., the subscriber of theSSP's services. Furthermore, transmission of packetized data (e.g.,through TCP/IP messages) over the Internet 22 allows for flexibility indata transmission. For example, the user and/or the SSP 18 may transmita TCP/IP emergency request message or Internet e-mail with an indicationor message flag set to indicate, to the corresponding carrier network14, 78 or 80 and/or the Internet 22, that the transmitted message begiven a designated priority (e.g., highest priority) over other pendingdata packets to be sent over the carrier network and/or the Internet 22.Such a “marking” of messages may be permitted when the carrier network14, 78 or 80 or the Internet 22 implements a class-based service schemeas discussed hereinbefore.

An additional advantage of the Internet-based emergency message deliverymethods of FIGS. 8 and 9 is that the user need not wait for a free lineto speak with an operator at the ESC 12. The user may simply press thepanic button 24 (FIG. 4) to automatically send the emergency helprequest message or to call the SSP 18 over a dedicated contact numberprovided by the SSP 18. Message delivery to the ESC 12 over the Internet22 relieves the user of waiting to speak with an operator at the ESC 12or to reach an operator initially. Furthermore, in one embodiment, theuser may transmit audible messages without actually reciting the messagein the user's voice. Here, the IP device 20 (in the arrangement of FIG.8) or a similar circuit arrangement at the SSP 18 (in the arrangement ofFIG. 9) may convert the textual message (e.g., the user's personal,medical and contact information) to be transmitted to the ESC 12 into anaudio file containing a synthesized voice message corresponding to thattextual message prior to sending the audio file to the ESC 12 over theInternet 22. An operator at the ESC 12 may thus “listen” to the textfile upon receipt of the emergency message.

The foregoing describes exemplary embodiments of an IP device having abuilt-in panic button that may be implemented in hardware or software.Activation of the panic button by a user in need of emergency helpresults in automatic transmission of one or more TCP/IP messages overthe Internet to an emergency service center requesting emergency helpand identifying the user in need of such help. The emergency servicecenter may also communicate, e.g., via Internet e-mail, with the IPdevice (and, hence, with the user) prior to dispatching emergency help.A support service provider may commercially provide Internet-basedemergency message delivery services to its subscribers. This may beuseful in many situations, for example, when the person in need of helpis speech-impaired, disabled or in a situation that prevents that personfrom orally requesting emergency help. The resources of the Internet maythus be advantageously harnessed to provide emergency help.

While several embodiments of the invention have been described, itshould be apparent, however, that various modifications, alterations andadaptations to those embodiments may occur to persons skilled in the artwith the attainment of some or all of the advantages of the presentinvention. It is therefore intended to cover all such modifications,alterations and adaptations without departing from the scope and spiritof the present invention as defined by the appended claims.
